Thanks Jae ... those articles are very useful!
I'd really like any information relating to the requirement for air entrained concrete in a freezer topping slab ... I'm in Northern Australia so there is no problem with freezing whilst the concrete is curing and hardening. We can take the temp...

Help!
I'm trying to figure this out ... any help would be appreciated.
